just got hold of 2 bags of black sand today and just finished putting theminto my A growout tank, thinking that it would intensify their colours more. prior to the new change in substrate the tank wasbare bottom'and the light would reflect fromunderneith the fish and it did look amazing (as shown in the photo's in the previous pages. . . an hour later after putting in the new black sand allmy fish looks darker and colour has saturated. pearsei almost grey/charcoal and argenteas grey. . . hmmm will they color up? or is this the downside of having black sand?
